Online Banking Authentication And Network Security Design And Implementation

The Internet has played a key role in changing the method of interaction and the action of business today. Nowadays,with the rapid development of e-business,E-bank has been widely used in daily-life and it has become one of the most important business of bank. At the same time,the security of online E-bank is becoming a serious and great subject of society and bank industry.In this thesis, a whole set of scheme for E-bank has been presented and realized that based on the existing E-bank system,and from the viewpoint of promoting networks security.. It realizes the low-cost running,and provides easy interface for customers by which is based on the online fingerprint identification and combines the fingerprint identification algorithm,encryption algorithm,and the real trading system of net-bank. The advantages include a new-developed method of fingerprint identification that is the first time in China to combine fingerprint identification algorithm with net-bank truly in use,it can substitute traditional person identification way by cipher, without the shortcoming of low-security and being easily forgotten. At the other hand,it is corresponding to the existing system very well.The thesis analysis the intrusion detection techniques of e-bank network, and gives an algorithms about misuse detection and anomaly detection, which are the two main methods of intrusion detection,the two algorithms shows good result in the experiment of chapter 5. The improved BHM matching algorithms can find out the known intrusions while the anomaly detection algorithms based on probability and statistics can detect the unknown intrusions.According to the result of experiment, the system can guarrantee the access security of the bank and detect most of known intrusions and some unknown intrusions to bank network, and satisfy the demand of networks security of the banks.
